Struct Color 

pub struct Color {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

Straight (unpremultiplied) sRGB color, components 0..=1.

Premultiplication happens at the GPU boundary (premultiplied()), and valo blends in sRGB space — the CSS/Skia-compatible look. Linear-light blending and wide gamut are deliberately deferred: when they land, this type stays and the conversion moves into the uniform-fill path.

Fields

r: f32

g: f32

b: f32

a: f32

Implementations

impl Color

pub const TRANSPARENT: Color

pub const BLACK: Color

pub const WHITE: Color

pub const fn rgba(r: f32, g: f32, b: f32, a: f32) -> Self

pub const fn rgb(r: f32, g: f32, b: f32) -> Self

pub fn from_rgba8(r: u8, g: u8, b: u8, a: u8) -> Self

From 8-bit sRGB (the CSS #rrggbbaa layout).

pub fn with_alpha(self, a: f32) -> Self

pub fn components(self) -> [f32; 4]

Straight components in draw order [r, g, b, a].

pub fn premultiplied(self) -> [f32; 4]

Alpha-premultiplied components in draw order [r, g, b, a] — what the uniform fill hands the blender.

pub fn is_opaque(self) -> bool
